Shallow snowdrifts in isolated cases avalanche prone
Avalanche danger is low. Snowdrifts can be problematic. Isolated small snowdrift accumulations can be triggered by minimum additional loading in steep terrain adjacent to ridgelines in W-E-SE aspects. Dangers of being swept along and of taking a fall outweigh those of being buried in snow masses. In particular in the Allgäu region it cannot be excluded that isolated smaller glide-snow avalanches trigger naturally on very steep slopes with smooth ground.

Circumvent small-scale snowdrifts. Danger of falling outweighs that of being buried in snow masses.
Avalanche danger is moderate above 2000m, below that altitude danger is low. Snowdrifts are the main problem. Slab avalanches that are mostly small can be triggered by minimum additional loading. Avalanche prone locations are found in steep ridgeline terrain in NW-E-SE aspects and in wind-loaded gullies and bowls. The frequency of avalanche prone locations increases with ascending altitude.
Snowpack
On the shady side the snowpack surface is powdery. In ridgeline terrain, small-scale snowdrifts will accumulate during the course of the day which will partly be deposited atop loose snow layers. The snowdrifts are prone to triggering. At high altitudes there are still layers consisting of faceted crystals more deeply embedded in the snowpack close to crusts. However, these are now very unlikely to trigger. At intermediate altitudes the old snowpack is thoroughly moist, wet at the ground in places.
Tendency
Avalanche danger levels will recede slowly.

On very steep slopes over smooth ground, it cannot be excluded that smaller glide-snow avalanches can release spontaneously.
